Inverter

Inverters are essential for feeding solar power into the mains grid

The inverter is an essential component of the solar array. It converts the direct current into alternating current so that it can be fed into the grid. The inverter also makes sure that the system immediately shuts down when are faults in the grid. Inverters are also used for providing electricity in so-called island systems, i.e. in a closed power system that is not connected to the grid, such as in a caravan or in remote cabins. Here, the solar power generated is saved in banks of batteries by the inverter. When buying, always make sure that the inverter is compatible with the solar modules and the other components.

There are three basic categories of inverters. Some inverters are suitable for single-phase alternating current, others are for triple-phase rotary current. Large central inverters are of no interest for domestic use as they are intended for extremely high efficiencies, take up lots of space and are predominantly used by professional solar energy producers.

Sinus inverters should be considered for domestic use as they provide sensitive devices such as televisions and computers with reliable energy. In general, the branded products which have dominated the market include the likes of SMA inverters, Solarmax inverters, Kostal inverters, SolarEdge inverters and Kaco inverters. The cost of an inverter varies by model and intended use.

To test the performance of a solar array, you can connect a solar log; this is attached to the inverter and measures input and output performance as well as recording any faults. The results can be displayed in tables or as a graph, although an internet connection is required for this.

SMA Grid Gate

897.02 €

SMA Grid Gate, Grid and plant protection compliance with rules and standards for plants from 30 kVA

Simple, reliable and typical for SMA – the solution for PV plants in Germany with more than 30 kVA on the low-voltage grid. The SMA Grid Gate is the ideal solution for regulation-compliant plant commissioning according to VDE-AR-N 4105 because it provides the binding grid and plant protection needed as of 2012. It is compatible with all plant sizes and inverter types provided they offer integrated islanding detection, as all SMA inverters do. In addition, it offers the advantage of simple installation using top-hat rail mounting. The user-friendly display permits convenient menu navigation and provides information on the current grid data or device status, for example. Reliable Complies with the new application rule VDE-AR-N 4105 Set up with single-fault tolerance Flexible It is binding for all PV plants in Germany with more than 30 kVA Universally applicable Simple With the default settings, no parameterization is needed Easy installation due to top-hat rail mounting Easy to use Informative display Display of all current power distribution grid and device data
